Abstract: An apparatus includes a heater for converting a filament of extrusion material into thermoplastic material. The heater has a channel configured to change the cross-sectional shape of the filament to a cross-sectional shape that has a greater surface area than the surface area of the filament before the heater receives the filament. The channel of the heater can also be configured to drive the center portion of the filament toward the heated walls of the channel and to mix thermoplastic material in the channel while exposing the center portion of the filament to the heated wall of the channel.

Abstract: A method for compensating for inoperative ejectors in a three-dimensional object printer has been developed. A printer detects an inoperative ejector in a printhead. The printer identifies functional ejectors that print at locations adjacent to locations where the inoperative ejector fails to print a drop. The printer modifies firing signals for the functional ejectors so those ejectors print drops having an increased drop volume at the locations adjacent to locations where the inoperative ejector fails to print a drop. The printer prints a first layer of material drops using the modified firing signals. The printer advances the printhead in the cross-process direction between layers so that locations where the inoperative ejector fails do print a drop do not coincide between layers.

Abstract: An extruder assembly for a three-dimensional object has an extrusion slot to enable faster three-dimensional object printing with greater precision. The extruder assembly includes an extruder body having an extrusion slot to enable a continuous filament of material to be extruded through the extrusion slot and at least one actuator operatively connected to the extruder body. The at least one actuator is configured to translate the extruder body in a horizontal plane and rotate the extruder body about a rotational axis.

Abstract: A method for compensating for inoperative ejectors in a three-dimensional object printer has been developed. A printer generates half-tone data for a material for each layer of a three-dimensional object. The printer detects half-tone data that corresponds to an inoperative ejector of a printhead. The printer modifies the half-tone data by moving the half-tone values corresponding to the inoperative ejector to adjacent positions within the generated half-tone data in which a zero half-tone value is stored. The printer operates the printhead with reference to the modified half-tone data to print the three-dimensional object.

Abstract: An inkjet printer is configured to apply a coating material to an imaging surface before an ink image is formed on the surface. At least one optical sensor generates image data of the coating on the imaging surface and identifies a thickness of the coating material. Components of the coating material applicator can be adjusted to keep the thickness of the coating material within a predetermined range.

Abstract: An inkjet printer estimates ink usage in the printer with reference to image pixels and a history of inkjet firing for each inkjet. The printer includes an apparatus that generates an ink mass for each image pixel with reference to the image pixel and a predetermined number of previously ejected image pixels and identifies a total ink mass measurement for a printhead with reference to the ink masses generated for the image pixels of an image to be printed by the inkjet printer.

Abstract: A method of operating a three-dimensional (3D) metal object manufacturing apparatus selects operational parameters for operation of the printer to form conductive metal traces on substrates with dimensions within appropriate tolerances and with sufficient conductive material to carry electrical currents without burning up or becoming too hot. The method identifies the material of the substrate and the bulk metal being melted for ejection and uses this identification data to select the operational parameters. Thus, the method can form conductive traces and circuits on a wide range of substrate materials including polymeric substrates, semiconductor materials, oxide layers on semiconductor materials, glass, and other crystalline materials.

Abstract: A three-dimensional object printer includes a controller that operates at least one ejector to place a layer of photopolymer material on a substrate. The controller is configured to cure the ejected photopolymer layer partially and position fiber on the cured layer before continuing to eject photopolymer material onto the fibers. The fibers can be loose or organized into a mesh. The pieces of mesh position on a cured layer can be pre-cut or a cutting device can be operated to cut pieces of mesh having a shape that corresponds to the shape of the layer of photopolymer material. The fibers reinforce the layers of photopolymer material and add strength and durability to the overall part being formed with the photopolymer material.

Abstract: An extruder has a valve assembly configured to move pins to open and close the nozzles in a multi-nozzle extruder head independently. The pins of the valve assembly that are driven by actuators into and out of engagement with nozzles in the extruder head are positioned within sleeves that extend between the valve assembly and the extruder head. A gap is provided between the extruder head and the end of the sleeves proximate the extruder head to enable thermoplastic material leaking from the extruder that contacts the pins to remain in a melted or plastic state so the thermoplastic material does not interfere with the movement of the pins.

Abstract: A method for operating a three-dimensional object printer compensates for inoperative ejectors. The method identifies image data values associated with an inoperative ejector that stored in a memory with other image data values for a three-dimensional object to be printed by the three-dimensional object printer. The method replaces the image data values associated with the inoperative ejector with image data values associated with an operative ejector that correspond to a material that is different than a material ejected by the inoperative ejector and operates a plurality of ejectors with reference to the other image data values and the replaced image data values to enable the operative ejector to eject drops of the material that is different than the material ejected by the inoperative ejector into the three-dimensional object at positions where the inoperative ejector would have ejected material.
